Abstract

Cette invention concerne des compositions chimiques polymères, des procédés de synthèse et des procédés de fabrication de dispositifs concernant des polymères capables de présenter une mémoire de forme et qui peuvent, dans un premier temps, être polymérisés en une structure polymère linéaire ou ramifiée, présentant des propriétés thermoplastiques, puis être traités pour obtenir un dispositif par des procédés habituellement utilisés pour les fusions, les solutions et les dispersions de polymère, puis être réticulés pour obtenir un polymère thermodurcissable à mémoire de forme conservant la forme qui lui a été conférée.
